The air conditioner has an air conditioning unit and an air conditioningcontroller for controlling the air conditioning unit. The aircontrolling controller has a display displaying a graphical informationand a touch panel positioned on the display and on which an operatortouches for controlling the air conditioning unit. Such touch panel isdescribed in Japanese laid open patent publication 2010-159922.

In the case a malfunction of the touch panel caused by an electrostaticfor example is occurred, an operator may reset such malfunction byturning off and on a power switch of the air controlling controller.However, the operator should consume a rather long period while thepower switch is turned off and turned on.

SUMMARY

The object of the present disclosure is to provide the air conditioningcontroller which is convenience to reset the malfunction of the touchpanel.

An air conditioning controller of the first disclosure has a displaydisplaying a graphical information, a touch panel positioned on thedisplay and on which an operator touches for controlling an airconditioning unit, a touch IC for detecting a change of a staticelectricity occurred on the touch panel when the operator manipulatesthe touch panel, and a controlling part sending a commanding order to anair conditioning unit by receiving a signal detected by the touch IC.

The controlling part determines whether an IC resetting condition is setby using the operator's manipulation manipulating the touch panel andresets the touch IC when the IC resetting condition is detected while anoperation of the air conditioning controller is kept.

As the touch panel detects whether or not the operator touches the touchpanel as well as the position of the finger of the operator by using achange of an electrostatic when the finger of the operator touches thetouch panel, the electrostatic may cause a malfunction such as a freezeof the touch panel. Such malfunction may be reset when the operatorturns the power switch off and turns the power switch again on. However,the operator should wait a rather long period while the power switch isturned off and on. Such chance making the operator wait may increase inaccordance with the function of the touch panel being increased.

As to the first disclosure, the controlling part resets the touch ICwhen the controlling part detects the IC resetting condition while thecontrolling part maintains the operation of the air conditioningcontroller. As the controlling part of the first disclosure detects theIC resetting condition by using the operator's manipulation manipulatingthe touch panel, the malfunction of the touch panel could be resetwithout the operator's additional operation. Accordingly, the operatordoes not have to turn off and on the power switch.

As the controlling part of the first disclosure detects the IC resettingcondition not using an information from the touch IC but using theoperator's manipulation, a diagnosing function of the air conditioningcontroller is achieved without extraordinal censing circuit.

As to the second disclosure, the air conditioning controller further hasa detector for detecting a resetting manipulation information caused bythe operator's manipulation including at least one of a manipulatingstrength and a manipulating interval. The controlling part of the seconddisclosure decides a resetting manipulation in accordance with theresetting manipulation information detected by the detector anddetermines whether or not the IC resetting condition is set by usingdetected the resetting manipulation.

In the case the malfunction of the touch panel is occurred, the operatormay push the touch panel with more power and/or may push the touch panelmore times within a short period. The detector of the second disclosuredetects the IC resetting condition by using such operator's behavior.

As to the third disclosure, the detector is located on the touch paneland has at least one of sensing function of an acceleration sensing forsensing an acceleration of the touch panel and a pressure sensing forsensing a pressure applied on the touch panel. The controlling part ofthe third disclosure determines the IC resetting condition by using atleast one information from the acceleration sensing and the pressuresensing.

Since, the detector of the third disclosure is positioned on the touchpanel, the detector could detect the operator's behavior applying on thetouch panel more effectively.

As to the fourth disclosure, the controlling unit stores an informationrelating to the resetting manipulation and adjusts the resettingcondition in accordance with stored the information.

The resetting manipulation may be varied between the operators. As thecontrolling unit of the fourth disclosure stores such resettingmanipulation of each of the operators and adjusts the resettingcondition in accordance with stored the information, such differencebetween the operators could be adjusted. Accordingly, the chance ofunnecessary reset of the touch IC due to the difference of the operatorscould be effectively reduced.

As to the fifth disclosure, the controlling part maintains a graphicalinformation displayed on the display while the touch IC is reset. In thecase if the graphical information displayed on the touch panel ischanged or disappeared on the display when the touch IC is reset, theoperator feels uncomfortable. As the fifth disclosure maintains the samegraphical information on the touch panel, such uncomfortable feeling ofthe operator is effectively avoided.

As to the sixth disclosure, the controlling part does not run itsoperation within a predetermined period when the touch IC detects theoperator's manipulation within the predetermined period after the resetof the touch IC is completed.

Since the operator may push an icon displayed on the display many timesin a short while when the malfunction of the touch panel is occurred,the operator may continuously push the icon even after the resettingoperation of the touch IC is completed. In such case, the manipulationof the operator may occur unintentional operation. For example, in thecase if the operator continuously pushes a DOWN icon after the resettingoperation of the touch IC is ended, the target temperature may bereduced more than the operator's intention.

As the controlling part of the sixth disclosure does not run theoperation within the predetermined period when the operator manipulatesthe icon within the predetermined period after the completing theresetting operation of the touch IC, such unintentional operation of theoperator could be effectively avoided.

As to the seventh disclosure, the controlling part further detects a CPUresetting condition and resets the controlling part when the CPUresetting condition is detected. The controlling part memorizes a numberof the IC resetting condition, decides whether or not the CPU resettingcondition is detected by using the number of the IC resetting condition,and resets the controlling part when the CPU resetting condition isdetected.

In the case when the IC resetting condition is detected more than apredetermined number within a predetermined period, the malfunction maybe occurred in the controlling part itself. Therefore, the controllingpart of the seventh disclosure resets the controlling part itself whenthe CPU resetting condition is detected. The seventh disclosurediagnoses the controlling part in accordance with the memorized numberof the IC resetting condition.

As to the eighth disclosure, the controlling part does not indicate theIC resetting condition while the touch IC is reset but indicates the CPUresetting condition while the controlling part is reset. Since thechance of the CPU resetting condition is relatively small, thecontrolling part of the eight disclosure indicates such CPU resettingcondition on the display, so that the operator could understand the CPUresetting condition is occurred. On the other hand, since the chance ofthe IC resetting condition is relatively large, the controlling part ofthe eight disclosure does not indicate the IC resetting condition on thedisplay, so that the operator may not be bothered by the information ofthe IC resetting condition.

As to the nineth disclosure, a period for resetting the touch IC isshorter than a period for resetting the controlling part. The period forresetting the touch IC is about several milliseconds for example and theperiod for resetting the controlling part is about several seconds forexample. Accordingly, the controlling part memorizes a number of the ICresetting condition and decides whether or not the CPU resettingcondition is detected by using the number of the IC resetting conditionas described in the seventh disclosure.

As to the tenth disclosure, the air conditioning controller has adisplay displaying a graphical information, a touch panel positioned onthe display and on which an operator touches for controlling an airconditioning unit, a touch IC for detecting a change of a staticelectricity occurred on the touch panel when the operator manipulatesthe touch panel, and a controlling part sending a commanding order tothe air conditioning unit by receiving a signal detected by the touchIC.

The controlling part of the tenth disclosure detects an IC resettingcondition by using at least one of an acceleration information of thetouch panel and a pressure information applied on the touch panel andresets the touch IC when the IC resetting condition is detected while anoperation of the air conditioning controller is kept.

As the controlling part of the tenth disclosure detects the IC resettingcondition by using the operator's manipulation information such as anacceleration information of the touch panel and/or a pressureinformation applied on the touch panel and resets the touch IC when theIC resetting condition is detected, the reset of the touch IC is startedwithout operator's additional operation. As the controlling part of thetenth disclosure resets the touch IC without turning off and on thepower switch, the operation of the air conditioning controller could bekept while the resetting operation of the touch IC is done.

As to the eleventh disclosure, an air conditioner has an airconditioning controller of the tenth disclosure and an air conditioningunit for operating an air conditioning operation by receiving acommanding order from the air conditioning controller.

As the air conditioner of eleventh disclosure has the air conditioningcontroller of the tenth disclosure, the operator of the air conditionermay reset the touch IC without additional operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present disclosure is explained hereinafter relating to an airconditioner used in the building and/or housing.

As shown in FIG. 1, the air conditioner 10 has an air conditioning unit11 and an air conditioning controller 12 which is connected with the airconditioning unit 11 by radio frequency. The air conditioning controller12 controls an operation of the air conditioning unit 11 including anair conditioning mode (cool, heat, dehumidification, and ventilation), atarget temperature, an air volume (fan speed), and a direction of thewind. When an operator decides a commanding order, such order is sent tothe air conditioning unit 11 and the received air conditioning unit 11follows the commanding order.

The air conditioning controller 12 has a controller unit 20 as aportable apparatus the detailed of which is explained later. Thecontroller unit 20 has a CPU 51 which mainly controls the operation sothat the CPU works as a controlling part. A display 53 is connected withthe CPU 51 via a graphic IC 52 so that the graphic IC 52 controls thegraphical image displayed on the display 53 in accordance with thecommanding order from the CPU 51. An electrostatic capacitance typetouch panel 55 is connected with the CPU 51 via a touch IC 54. The touchpanel 55 is so accumulated with the display 53 that the touch panel 55locates on the front face of the display 53 and that the operator couldvisibly recognize the image displayed on the display 53

The touch IC 54 detects the change of the electrostatic capacitance ofthe touch panel 55 where the operator touches and sends the touchinginformation to the CPU 51. The CPU 51 decides whether or not thetouching information exists and the location where the operator touches.

The controller unit 20 also has a thermometer/humidity sensor 57detecting the room temperature and humidity and an acceleration sensor58 detecting the movement of the air conditioning controller 12. Boththe thermometer/humidity sensor 57 and the acceleration sensor 58 areconnected to the CPU 51 so that the detected information is transferredto the CPU 51. The room temperature and/or the humidity is displayed onthe display 53 in accordance with the commanding order from the CPU 51.The CPU has the reset function for resetting the touch IC 54 inaccordance with the detected information from the acceleration sensor58. The detail of the reset function is explained later.

The controller unit 20 is connected with the electric power source 45via an electric cable line 38 (shown in FIG. 3) so that 24V of electricvoltage from the electric power source 45 is supplied to the CPU 51, thegraphic IC 52 and the touch IC 54 via an electrical power supply line 61positioned in the air conditioning controller 12. The electric voltageis reduced from 24 B down to 3V by a regulator embedded in the CPU 51.The controller unit 20 also has a power switch 59 by which the operatorturns the controller unit 20 on and off.

The controller unit 20 has an internal battery 65 such as a couple of AAcell batteries in series configuration (3V of electric voltage). Theelectric power from the internal battery 65 is supplied to the CPU 51,the graphic IC 52 and the touch IC 54 via the electrical power supplyline 61 in the case when the electric power from the electric powersource 45 is not supplied.

As shown in FIG. 2, the air conditioning controller 12 has a holder 30which is able to hold the controller unit 20. As shown in FIGS. 3(a) and3(b), the holder 30 has a flat base portion 31 fixed on the surface ofthe wall of the room and a holding portion 32 positioned perpendicularto the base portion 31 so that the holder 30 is a box shape surroundingthe controller unit 20. In the case when the controlling unit 20 is heldin the holder 30 (holding position) the rear surface (right side of FIG.3(a)) of the controlling unit 20 contacts to the font surface (left sideof FIG. 3(a)) of the base portion 31.

The controller unit 20 is formed by a controller main part 21 and a caseunit 22 holding the controller main part 21 in such a manner that theoperating surface (displaying surface) of the controller main part 21 isnot covered. A notch portion 33 is formed the inner surface of theholding portion 32 of the holder 30 so that the notch portion 33contacts with a concave portion 23 formed in the case unit 22 when thecontrolling unit 20 is held at the holding position. As the holdingportion 32 is flexible, the operator may remove the controller unit 20out from the holder 30 by so deforming the holding portion 32 that thenotch portion 33 is disengaged from the concave portion 23.

A holder side connector 35 is fixed on the base portion 31 of the holder30. The holder side connector 35 is connected with the electric powersource 45 via the electric cable line 38. A controller unit sideconnector 25 is formed on the rear surface (right side of FIG. 3(a)) ofthe controlling unit 20 so that the controller unit side connector 25contacts with the holder side connector 35 when the controller unit 20positioned at the holding position. Accordingly, the electric power ofthe electric power source 45 is supplied to the electrical power supplyline 61 of the controller unit 20 via the electric cable line 38, theholder side connector 35 and the controller unit side connector 25.

In the case the controller unit 20 is removed from the holder 30 (thecontroller unit 20 in not positioned at the holding position), thecontrolling unit side connecter 25 disengages from the holder sideconnector 35 so that the electric power from the electrical power source45 is not supplied to the electrical power supply line 61 and supplysource of the electric power is switched from the electrical powersource 45 to the internal battery 65.

As the controller unit 20 has the touch panel 55, the operator could usealmost entire surface of the controller unit 20 as the operating areafor detecting the electrostatic change caused by the operator. However,the touch panel 55 also has a weak point that the static electricityfrom the operator causes the malfunction. Though such malfunction couldbe recovered by resetting the air conditioning controller 12 by turningoff and on the main power switch 59, the additional operation isrequired for the resetting operation and, therefore, the operator shouldwait for a moment. The additional explanation is explained by referringFIGS. 4 and 5 hereinafter.

FIG. 4 shows a main menu displayed on the display 81 which is the sameas the display 53 of FIG. 1 of the controller unit 20. The main menushows a various information includes a present mode, a present roomtemperature and a target temperature, an icon 82 for changing the mode,an icon 83 for changing the fan speed and an icon 84 for setting thetarget temperature. In the case the operator pushes one of the icons82-84, the graphical information displayed on the display 82 is changedfrom the main menu to an operating menu.

The example of the operating menu of the temperature setting menu isshown in FIG. 5. An UP icon 87 increasing the target temperature and aDOWN icon 88 decreasing the target temperature and the targettemperature 86 are displayed on the temperature setting operating menu.FIG. 6 shows the operation of the operator for changing the targettemperature. At the timing when the CPU 51 receives the operatingcommand of the operator, the CPU 51 sends such operating command to theair conditioning unit 11 and changes the target temperature 86 displayedon the display 81.

In the case if the static electricity from the operator causes themalfunction on the touch IC 54, the touch IC 54 could not work andtherefore the touch IC 54 could not sense the change of theelectrostatic capacitance even the operator touches the touch panel 55.Accordingly, the graphical information on the display 81 is frozen andthe target temperature is not changed though the operator touches the UPicon 87 or the DOWN icon 88.

The CPU 51 of this embodiment has a resetting function for resetting thetouch IC 54 by using the information from the acceleration sensor 58. Inother words, the resetting operation for resetting the touch IC 54 isincluded within a regular operation done every setting timing (1millisecond for example). Such resetting operation is explainedhereinafter by referring FIG. 7.

Whether or not a flag showing the reset is installed in the RAM of thecontroller unit 20 is decided at first (step S101) of the resettingoperation. If no flag is detected (NO), whether or not the controllerunit 20 is moved, in other words, whether the accelerating signal formthe acceleration sensor 58 is increased more than the predeterminedthreshold accelerating level is detected is decided (step S102). If noaccelerating signal more than the predetermined threshold level is sentform the acceleration sensor 58 (NO), the resetting operation ends. Ifthe accelerating signal more than the predetermined threshold level issent form the acceleration sensor 58 (YES), then the resetting operationmoves next step (step S103).

The interval of the movement is calculated in the step S103 by using N+1times movement accumulating the last movement and N (more than 2 forexample) times previous movements. Whether or not the calculatedinterval of the movement is shorter than a predetermined standard periodis decided in the step S104. If the interval is shorter than thepredetermined standard period (YES), the resetting operation moves nextstep (S105).

The counting operation of the various counters including the timercounter for counting the above described interval (step S103) is resetat the step S105. The operation of the touch IC 54 is reset at the stepS106 so that the frozen condition above described is ended and that thedetecting function of the touch IC is recovered. The flag indicating theresetting operation is set at the step S107, then the resettingoperation ends. The required period for resetting the touch IC is aboutseveral millisecond so that the resetting period is shorter than thatthe operator resets the CPU 51 by using the power switch 59 (5 secondsfor example).

Back to the step S104, in the case the interval is longer than thepredetermined standard period (NO), the resetting operation moves to thestep S108. Whether the last detected acceleration signal is greater thana predetermined standard value is decided at the step S108. Thepredetermined standard value of this step S108 is greater than thepredetermined threshold level of the step S102.

In the case when the last detected acceleration signal is smaller thanthe predetermined standard value (NO), the resetting operation ends. Inthe case when the last detected acceleration signal is greater than thepredetermined standard value (YES), the resetting operation moves thestep S109. Whether the greater acceleration signal greater than thepredetermined standard value continues more than two (2) times isdecided at the stop S109. No continuing of the greater accelerationsignal is detected (NO), the resetting operation ends. The continuationis detected (YES), the resetting operation ends after the stepsS105-S107 are operated.

Back to the step S101, in the case the flag is found in the RAM (YES),the resetting operation moves to the step S110. Whether the resetoperation of the touch IC 54 is completed is decided at the step S110 bythe period counted by the timer counter from the beginning of theresetting operation being longer than the required resetting period(several millisecond for example). In the case if the completion of thetouch IC resetting is not decided at the step S110 (NO), the resettingoperation ends. If the step S110 decides the completion (YES), theresetting operation ends after the flag in the PAM is deleted at thestep S111.

The graphical information displayed on the display 81 is maintainedduring the resetting operation and no signal indicating the completionof the resetting operation is alerted so that the resetting operationdoes not make the operator a bothersome feeling.

FIG. 8 explains the normal operation of the touch panel 55. Every timing(ta1, ta2) when the operator pushes the operating icon (the DOWN icon 88for example) the temperature displayed on the display 81 is changed(“24”-“23”-“22”). As the operator visibly checks the numeral on thedisplay 81, the interval between the operator's pushing operation (ta1,ta2) may be a certain amount of period.

FIGS. 9 and 10 show an abnormal operation and the resetting operation ofthe touch panel 55. When the operator pushes the operating icon (theDOWN icon 88) at the first timing (tb1) the temperature displayed on thedisplay 81 is changed (“24”-“23”) but the static electricity from thefinger of the operator may cause the malfunction on the touch IC 54. Sothat even the operator pushes the operating icon (the DOWN icon 88) atthe next timing (tb2) and the timing after the next (tb3) the numeraldisplayed on the display 81 is not changed but continues as “24”. Theoperator who found the continuing numeral of “24” pushes the operatingicon (the DOWN icon 88) in a short period so that interval between thepushing timing tb3, tb4, and tb5 of the abnormal condition is shorterthan the standard timing tb1 and tb2 of the normal condition. Suchshorten of the period could be calculated at the timing of tb5.Accordingly, the touch IC 54 could be reset by using the movement (theoperation of the touch panel 55, the pushing operation of the operatingicon) as the trigger. Namely, the step S103 and the step S104 of theresetting operation is carried out by using the operator's suchoperation that the operator pushed the operation icon in a short while(tb3, tb4 and tb5). The resetting operation of the touch IC 54 starts atthe timing of tb5 and ends at the timing of tb6, so that the nextpushing operation of the operator at the timing (tb7) could reduce thetarget temperature from “23” down to “22”.

As the shown in FIG. 10, the operator who found the continuing of thetemperature of “23” pushes the operating icon (the DOWN icon 88) withstronger power so that the movement of the controller unit 20 caused bysuch operator's action makes the acceleration signal more than thepredetermined standard value. Such operator's behavior is occurred atthe timing of tc4, tc5 and tc7. The resetting operation of the touch IC54 starts by using the movement (the operation of the touch panel 55,the pushing operation of the operating icon) as the trigger. Namely, thestep S108 and the step S109 of the resetting operation is carried out byusing the operator's such manipulation that the operator pushed theoperation icon with stronger power. The example shown in FIG. 10 startsthe resetting operation of the touch IC at tc5 and ends the resettingoperation at tc6, so that the operator's manipulation at tc7 couldreduce the target temperature from “23” down to “22”.

The malfunction of the touch panel 55 may not be caused by the touch IC54 but be caused by the CPU 51 so that the CPU 51 starts its ownresetting operation (resetting operation for the CPU 51) when aplurality of resetting operations of the touch IC are occurred in ashort period. The resetting operation for the CPU 51 as one of theregular operations is done by the CPU 51.

As shown in FIG. 11, the resetting operation for the CPU 51 starts tocheck whether or not the resetting operation of the touch IC 54 (stepS201) exists. If no reset of the touch IC 54 is found (NO), theresetting operation for the CPU 51 ends. If the reset of the touch IC 54is found, then decide whether the counted number of the reset of thetouch IC 54 reaches to the predetermined number (3 times for example)within a predetermined period at the step S202. If the counted number ofthe reset of the touch IC 54 is less than the predetermined number, theresetting operation for the CPU 51 ends. If the counted number of thereset of the touch IC 54 reaches to the predetermined number within apredetermined period, a various counters for resetting the CPU includingthe counter for counting the reset number of the touch IC and the timercounter measuring the time period are reset at the step S203. After theresetting of the counters at the step S203, the resetting operation forthe CPU 51 is carried out at the step S204. During the resettingoperation for the CPU 51, the sign showing the CPU 51 is under resettingcondition such as “please Wait” shown in FIG. 12 is displayed on thedisplay 81.

The above described embodiment has following effects. The controllerunit 20 could reset the touch IC 54 while the controller unit 20 is keptits condition turned on when the resetting condition caused by theoperator (pushing in a short while, pushing with stronger power) isdetected. Namely, as the following operation done by the operator (thesetting operation of the target temperature for example) is used as thetrigger for the resetting operation of the touch IC 54, the resettingoperation starts automatically and the waiting period the operator waitsfor completing the resetting operation could be shortened.

Because the CPU 51 runs by using the information detected by the touchIC 54, it is difficult for the CPU 51 to finds the malfunction of thetouch IC 54. The CPU 51 of this embodiment decides the resettingcondition not by using the signal from the touch IC 54 but by using themanipulation of the operator so that the CPU 51 could start theresetting operation of the touch IC 54 without the complicated programof the CPU 51.

As the electrostatic capacitance type controller unit 20 of thisembodiment has the acceleration sensor 58 the operator's behaviorindicating the malfunction of the touch IC 54 could be effectivelyfound.

Compare to the conditions that the graphical information is changedduring the resetting operation and that no graphical information isdisplayed during the resetting operation, as the graphical informationdisplayed on the display 81 of this embodiment is kept the same image asthat displayed before the malfunction, the operator could wait theresetting operation without the bothersome feeling.

Since the alert indicating the resetting operation for the CPU 51 isdisplayed on the display 81, since the frequency of the resettingoperation for the CPU 51 is substantially small and since the period ofthe resetting operation for CPU 51 is longer than that of the resettingoperation of the touch IC 54, the operator could recognize the resettingoperation of the CPU 51 without the bothersome feeling.

The present disclosure may be modified as follows. The followingmodifications could be connected each other.

Any type of the switching element such as a bipolar transistor and/orMOFSET (metal-oxide-semiconductor field-effect transistor) is used forswitching the electrical power supply line 61.

The reset button by which the operator resets the touch IC 54 could bemade on the controller unit 20.

The holder side connector 35 and the unit side connector 25 of the abovedescribed embodiment is connected and disconnected in accordance withthe position of the controller unit 20. However, the holder sideconnector 35 and the unit side connector 25 may be switched between theconnecting position and disconnecting position by the operator while thecontroller unit 20 is stayed in the holder 30.

Though the air conditioning controller 12 of the above describedembodiment is a portable, the air conditioning controller could befixed. The other type such as a resistance membrane type, an opticaltype or an ultrahigh sonic surface elasticity wave type touch panel 55than the electrostatic capacitance type touch panel 55 could be used.

In the case if the operator manipulates the touch icon within apredetermined period after the resetting operation of the touch IC 54 iscompleted, the CPU 51 may not run the operation within the predeterminedperiod. As described above, and as shown in FIG. 13, since the operatormay push the icon many times in a short while (tb4, tb5, and tb7) whenthe malfunction of the touch panel 55 is occurred, the operator maycontinuously push the icon even after the resetting operation of thetouch IC 54 is completed. In such case, the manipulation of the operatormay occur unintentional operation. For example, in the case if theoperator continuously pushes DOWN icon 88 after the resetting operationof the touch IC 54 is ended (tb6), the target temperature may be reducedmore than the operator's intention.

As the CPU 51 of this modified embodiment does not run the operationwithin the predetermined period A (in FIG. 13) when the operatormanipulates the touch icon (at tb7) within the predetermined period Aafter the completing the resetting operation of the touch IC 54 (attb6), such unintentional operation (at tb7) of the operator could beeffectively avoided. The manipulation of the operator after thepredetermined period A (at tb8) could run the CPU 51 and reduce thetarget temperature down to “22”.

In the case if a plurality of operators manipulate the same controllerunit 20, the CPU 51 memorizes the operation of each operator in a memory51A (shown in FIG. 1). As the push strength and/or the push interval aredifferent between the operators, the CPU 51 adjusts the push strengthand/or the push interval depend on the operator so that the adjustedconditions of each of the operator could be used.

As explained above, the operator uses abnormal manipulation when themalfunction of the touch IC 54 is occurred. Such abnormal manipulationincludes the long tap, the flick, and the multitaps other than the abovedescribed push strength and the push interval. The acceleration sensor58 could detect these abnormal manipulations of the operator. The CPU 51starts the resetting operation of the touch IC 54 when the accelerationsensor 58 detects such abnormal operation.

A pressure sensor may be used for detecting the abnormal manipulation ofthe operator instead of the acceleration sensor 58. However, a pluralityof pressure sensors are required in order to detect the abnormalmanipulation precisely so that such detecting system using the pluralityof pressure sensors may be complicated. Accordingly, single accelerationsensor 58 is suitable for detecting the abnormal manipulation.

Though the CPU 51 of the above described embodiment uses both the pushpressure and the push interval for deciding the resetting condition ofthe touch IC 54, either one of the push pressure and the push intervalmay be used for deciding the resetting condition of the touch IC 54.

The acceleration sensor 58 may be positioned anywhere in the controllerunit 20 including the center of the controller and the corner of thecontroller 20.

The information indicating the resetting operation of the touch IC 54may be displayed on the display 81.

What is claimed is:
 1. An air conditioning controller, comprising; adisplay displaying a graphical information. a touch panel positioned onsaid display and on which an operator touches for controlling an airconditioning unit, a touch IC for detecting a change of a staticelectricity occurred on said touch panel when the operator manipulatessaid touch panel, a controlling part sending a commanding order to saidair conditioning unit by receiving a signal detected by said touch IC,wherein said controlling part determines whether an IC resettingcondition is set by using the operator's manipulation manipulating saidtouch panel and resets said touch IC when said IC resetting condition isdetected while an operation of said air conditioning controller is kept.2.
